sclaims. ,(Cl. 2li- 12) :This inventionrrelates to2window structures ofthe frictional supported sash type and slider-ail assemblies thereof andi the methodzoftproducing such: assemblies.

The main objects fof :this .invention are: First, to; provide an limproved i window .structure of the .typefin lwhich'the sash'may be .quickly inserted and removed and-includes spring biased :sash `slide rails.

Second, to :providefa unitary `sashf-s'lide rail assemblyl including adjusting Ascrews coacting with springbiased 'members mounted Von a jamb, one which permits the Vquiclrmounting anddetachingof :the Vslide railand the adjustment thereof to secure the desired biasing thrust -on the slide rails yto meet 'the `requirementsof thepar- ,.ticular window assembly.

`inventionis dened and pointed outin the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing,'in which:

Fig. 1 is an enlarged fragmentaryihorizontal sectionof a window construction embodying-my invention, the; slide rail supporting and adjusting screw being shownin full lines.

Fig. 2 is Ya fragmentary frontperspective view of 'the unitary sashslide railof my invention.

Fig. 3 is an enlarged fragmentary viewillustratingcertain steps of my method.

Fig. 4 is a fragmentary view illustrating theefnalfstep .ofthe method and apparatus4 forperforming i the same.

Fig. 5 is a plan view of a disc-like blank illustrating the rst step in thefmethod ofproducing the thrust element of the rail sash assembly embodying my invention.

Fig. 6 illustrates the second step in which the blank has been drawn or formed into a conical shape.

Fig. 7 is an enlarged sectional view showing the third step in the forming of the thrust element prior to the assembling step illustrated in Figs. 3 and 4.

In the accompanying drawing 1 represents the jamb or side rail of a window frame and 2 a stop thereof. 3 represents the vertical rail of a window sash having a longitudinal groove 4 therein. These parts are shown mainly conventionally except that the jamb is provided with an opening S adapted to receive means for springably biasing an element with which the screw 6 of the slide rail assembly coacts. The slide rail 7 is of inwardly facing channel section and is provided with a longitudinal rib 8 adapted to engage the longitudinal groove 4 in the sash rail 3.

The sash rail '7 is preferably provided with a plurality of supporting screws, as is illustrated in Fig. 2, but these are duplicates and therefore only one is illustrated and described in detail. The faces of the ribs of the sash rail have inwardly projecting or inwardly struck conical seats 9 therein adapted to rotatably support the peripherally conical heads 10 of the screws 6. l

atent Patented Sept. 17'., 1957 i2 `The-screw-rxhasan annular groove 11'at thebase of its "head in Awhich the inturned flange 112of the conical thrust member A113is engaged. The screw is desirably rotatable relative -to the conical thrust member which :should be understood, lhoweverythatmy inventionis not limitedftousewith such spring biasing means. The means illustrated lcomprises abase member l12 mounted lin "the fopeningS inthe-jarnb i1 and provided with forwardly projecting arms 13 terminating in inturned stops i14. Coiled springs 15 are sleevedover these arms to'vprojectbeyond the .ends lof .the arms.

The coacting thrust .member 16is provided with in -wardly Lprojecting arms V17 vdisposed in telescoping re- Ylation to thearms v13 and provided with outturned hoo'ks 18 which-coact with 'thehooks 140m the arms 13 to limit the outward movement ofthe thrust member under the .action of the springs 15. The thrust member is provided =with a spring abutmentmember 191with which the screw 6 coacts. Thescrew '6has1threaded engagement withthe `member d'9. Only .one sash is illustrated in Fig. lia frag- .mentof aslide rail for a second sashis shown.

The parts Aof the slide rail :assembly may be quickly -and rapidlyassembled with uniform results. The thrust .member and .its engagement with :the 'screw *whereby *the .screw is rotatably mounted on the slide frail 'is an important feature of my invention. In Figs. 5, '6 and 7 1 illustrate 4successive steps Vof forming the thrust fmember which serves Lthe double purpose of receiving -the `thrust .onthe screw and also coacting with the head o'fthe screw .in retaining the parts of `the=slide .rail assembly together. Fig. 5 illustrates a circular 4disc-like blank 19 ofsheet .metal having a central hole 20 therein. The second step vvis 'to form the blank i19/into'thecone shapeshown inlfFig.

'6 which for identification is `designated lby the fnumerafl 12.1. The third step is conforming rthe inner end Vof the Ipart Zito provide -a flange 22 around the hole (21)'. yIn assembling, lthe screw is inserted ythrough 'the vopening lin the `seat 9 with its hea'd 10 in supported 'engagement ."witb the inner side of the wall thereof.' The 'slide ra'ilwith the screw inserted therethrough `is -then positioned upon a bed member 24 having a raised conical portion 25 which ts into the outer end of the seat and in supporting engagement with the end of the screw as is shown in Fig. 4. The element 23 is then placed over the screw in supported engagement with the inner side of the conical seat of the rail. In this position the flange like portion 22 embraces the screw above the groove 11 therein, see Fig. 3.

The ram or upsetting member 26 has a conical recess 27 adapted to ttingly embrace the thrust element when the parts are in fully actuated position as shown in Fig. 4. The ram member has an annular shoulder 28 which, as shown in Fig. 3, engages the end of the flange portion 22 of the element. As the ram is actuated this ange portion 22 of the thrust member is turned inwardly and also portions above the ange are folded inwardly by the shoulder 2S until the inner end of the thrust member is turned to the position shown in Figs. 1 and 4 with the thrust member in retaining engagement with the groove. As the thrust is applied to the edges of the part 22 there is a tendency for the element 23 to bulge outwardly but that is limited by the wall 27, which when the ram 26 is fully actuated conforms and seats the thrust member against the inner side of the screw hea-d seat.

The head of the screw and the part 25 of the bed member fit within the seat to support the wall of the seat so they cannot be distorted during this operation. This assembling operation maybe very rapidly performedvand VNo. 559,226 but these details form no part of my present invention. The improvement of my invention illustrated is highly practical.

I have not attempted to illustrate or describe certain modications which I contemplate or which might be desirable for other types of window structures than that conventionally illustrated as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may `be desired.
